Android Google Map not showing my location?

Question

I am currently working on a Google Map current location application. Everything is good and there is no error detected.

When I run my application, Google Map is able to load but is not showing my current location.

So I put my logcat here and please someone help me. Is it related to the

"Asset path '/system/framework/com.android.media.remotedisplay.jar' does not exist or contains no resources."

? I did some research on this but could not find the solution.

What does this google map template looks like ? Empty tiles ? I suspect this has something to do with your key. — inmyth, Apr 25 '15 at 18:28
I mean my application on the emulator can only runs the basic google map, which is exactly the same as new porject -> choosing target android devices -> choose google map activity template. I have installed the necessary SDK like google play service in the SDK manager, and got all permissions I need. But my case is my application did not show my current location. Do I need to put my code here? — lemon, Apr 25 '15 at 18:46
I'm not going to create a new project to see it. Does the map show blank tile ? Or does it show a map somewhere off coast West Africa ? The first is the problem of key. The second is the position of lat,lng = (0, 0). You need to manually set your own location if that's the case. — inmyth, Apr 25 '15 at 18:58
The map shows somewhere off coast west africa, seems this is the the start point of google map having 0 lat and lng, but I could not get my current location. — lemon, Apr 25 '15 at 19:26

By default a map doesn't show your location. Location is provided by different service: Google Play location API (which supersedes Android location API).

This is a minimum code to implement it. First add these in your manifest

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Then you need to build a GoogleApiClient in your map Activity

public class MyMapActivity extends Activity {

 private GoogleMap googleMap;
 private GoogleApiClient mGoogleApiClient;
 protected Location mLastLocation;

  @Override
  public void onCreate(Bundle inState) {
  // do whatever initialization including one for googleMap
     mGoogleApiClient = new GoogleApiClient.Builder(this)
     .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {

          @Override
          public void onConnected(Bundle arg0) {
             // this is where you got your last location
             mLastLocation = LocationServices.FusedLocationApi
             .getLastLocation(mGoogleApiClient);
             // then center on map
             LatLng mLatLng = new LatLng(mLastLocation.getLatitude(),
             mLastLocation.getLongitude());
             googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom
             (mLatLng, 14), 1000, null);

           }

           @Override
             public void onConnectionSuspended(int arg0) {
           }

     })
     .addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {

           @Override
           public void onConnectionFailed(ConnectionResult conResult) {
             if (conResult.hasResolution()){
              try{
                conResult.startResolutionForResult(MyMapActivity.this,
                CONNECTION_FAILURE_RESOLUTION_REQUEST);
               }catch(SendIntentException e){
                    e.printStackTrace();
               }                    
              }
             }})
     .addApi(LocationServices.API)
     .build();
  }

}


  @Override
  protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
  }

  @Override
  protected void onStop() {
    super.onStop();
    mGoogleApiClient.disconnect();
  }

This is official how-to for reference.

The next problem is you are using an emulator so you need to emulate a mock position. This link will better explain how: How to emulate GPS location in the Android Emulator?

Thanks inmyth. The last link is the thing I am looking for, its the problem about my emulator console. These few days I was trying to solve the location problem in many different ways and now my problem is finally solved. Thanks again!!! — lemon, Apr 26 '15 at 11:09
I have 1 more query want to clear, if I want to show the current location without emulate a mock position, the only way is testing on a real device, Am I correct? — lemon, Apr 26 '15 at 13:46
Yes. In practice device will get present location whose accuracy depends on the access locations settings in the manifest. — inmyth, Apr 26 '15 at 14:05
